Using it on 6.5cm with h4350 it is not repeatable. All powder charges were verified on a sartorius scale with resolution to 0.02 grain, about 1 kernel of powder. The daa powder check sometimes sounded off and sometimes not on verified charges.

After the powder was weighed on the sartorius scale the case was filled thru a forester long neck powder funnel then placed back in the Dillon 750 for further cycle . The first of which was the daa powder check.

The brass end of the daa powder check would not fit thru the case neck so I had to use the plain rod end. There should be something in between using the plain steel end of the rod and the supplied larger brass end which was too big for the 6.5cm case neck. A bigger foot over the plain steel rod end may have been more repeatable.

Also the sensitivity of finding the sweet spot of the alarm can be a pain to find with the rod setting on a good powder charge. By the time you get the wrench into the magnet set screw you are compressing the powder charge, which makes the adjustment of the magnet void. Even pulling the rod out, marking magnet location and then adjusting magnet position was no help. They should have kept the sensitivity adjustment screw on the unit itself, or one that fine adjusts the center point of the go and no go point of the height range.

In short they need to come up with another brass end that will fit 223 and 6.5, they need to come up with a fine screw adjustment on the daa not the rod that adjusts the center point of the magnet sweet spot of the desired powder charge. As it now comes it may be 50% reliable, but 50% for a alarm is not acceptable. Concept is good, it just is not ready for prime time, needs more refinement. Tried for a 50% rating in stars like the unit performs but the program will not allow, so I settled at 2.

Awesome addition for your safety! Well made, and very easy to adjust for close monitoring of your powder charges during the reloading process.

works great and the new plunger rod with the brass shoe is the best way to avoid spill our the case the powder

I got 2 of the powder checker as I have 2 Dillon 750 one set up for 9mm the other .44mag target loads . Dont need it for the 9mm as 5gr fills the case so a quick look you can see its ok or not but it takes that one point off the check list . Case feed . Primer. power ( no need ) bullet head .
but as for the .44mag set up for 7gr in that case you can not see so before I got this I had to look with a torch through the die hole that this checker now fits.
I feel a lot safer now knowing that the right charge is in the cases .
it is easy to set up too

Much better, more forgiving and more accurate than the stock powder cop! Measures quickly and triggers off the case rim so very few annoying mis-triggers and does not go off if you skip a case.

I have purchased two magnetic powder check measures, they are simple to set up and work very well.
